Green earthquake (Magnitude 5.5M, Depth:82.29km) in Japan 01/08/2026 02:48 UTC, 1.5 million in MMI IV

Summary

Single-source GDACS detection — awaiting independent verification. A magnitude 5.5 earthquake at a depth of 82.29 km was detected in Japan on 1 August 2026, potentially exposing an estimated 1.5 million people to MMI IV shaking. The medium-depth event reduces the likelihood of severe surface damage, but the lack of corroborating news reports makes the operational impact uncertain.

Supply chain impact

No commodities or chokepoints are directly mapped to this event; second-order effects depend on how the situation escalates. If confirmed, light shaking across a populated area could cause brief, localized disruptions to logistics and manufacturing through power fluctuations or precautionary transport halts, but the depth and moderate magnitude suggest any interruptions would be short-lived.

Watch points

• Verification of the event by the Japan Meteorological Agency or major news outlets to confirm location, intensity, and any reported damage.
• Status of regional road and rail networks in the affected prefecture for any temporary service suspensions that could delay last-mile deliveries.
• Aftershock activity that could trigger renewed precautionary shutdowns at industrial or logistics facilities.
